VideoView播放视频

VideoView是安卓自带的视频播放控件，可以通过两种方式播放，一种是访问网络，还有一种是访问本地视频

第一种：访问网络

代码：

package com.example.day08;

import android.content.Intent;
import android.net.Uri;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.MediaController;
import android.widget.Toast;
import android.widget.VideoView;

public class VideoActivity extends AppCompatActivity implements View.OnClickListener {
    VideoView videoView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_video);
        init();
    }

    private void init() {
        videoView = findViewById(R.id.videoview);
        //按钮监听事件
        findViewById(R.id.play).setOnClickListener(this);
        findViewById(R.id.pause_1).setOnClickListener(this);
        findViewById(R.id.stop_1).setOnClickListener(this);

        videoView.setMediaController(new MediaController(this));//获得控制器

    }

    @Override
    public void onClick(View v) {
        switch (v.getId()){
            case R.id.play:
                Uri  uri = Uri.parse("https://media.w3.org/2010/05/sintel/trailer.mp4");
                videoView.setVideoURI(uri);//设置播放哪个资源
                videoView.requestFocus();
                videoView.start();
                Toast.makeText(this, "播放", Toast.LENGTH_SHORT).show();
                break;
            case R.id.pause_1:
                videoView.pause();
                Toast.makeText(this, "暂停", Toast.LENGTH_SHORT).show();
                break;
            case R.id.stop_1:
                videoView.stopPlayback();
                videoView.resume();
                Toast.makeText(this, "停止", Toast.LENGTH_SHORT).show();
                break;
        }
    }
}

此控件自带暂停与快进

第二种：访问本地

package com.example.day08;

import android.content.Intent;
import android.net.Uri;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.MediaController;
import android.widget.Toast;
import android.widget.VideoView;

public class VideoActivity extends AppCompatActivity implements View.OnClickListener {
    VideoView videoView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_video);
        init();
    }

    private void init() {
        videoView = findViewById(R.id.videoview);
        //按钮监听事件
        findViewById(R.id.play).setOnClickListener(this);
        findViewById(R.id.pause_1).setOnClickListener(this);
        findViewById(R.id.stop_1).setOnClickListener(this);

        videoView.setMediaController(new MediaController(this));//获得控制器

    }

    @Override
    public void onClick(View v) {
        switch (v.getId()){
            case R.id.play:
            	//去获取本地路径
                String path = Environment.getExternalStorageDirectory().getAbsolutePath();
                videoView.setVideoPath(path);//将路径设置给资源
                videoView.requestFocus();
                videoView.start();
                Toast.makeText(this, "播放", Toast.LENGTH_SHORT).show();
                break;
            case R.id.pause_1:
                videoView.pause();
                Toast.makeText(this, "暂停", Toast.LENGTH_SHORT).show();
                break;
            case R.id.stop_1:
                videoView.stopPlayback();
                videoView.resume();
                Toast.makeText(this, "停止", Toast.LENGTH_SHORT).show();
                break;
        }
    }
}
